Ice machine for making tube ice

Abstract

The invention relates to an ice machine for making tube ice, which comprises an evaporator, a round heat exchange tube and a full closed heat exchanger. The evaporator is a vertical shell and tube evaporator and is controlled by a control system, a vertical heat exchange tube is arranged in the shell of the evaporator and contains water supplied constantly from outside and flowing from top to bottom, the shell is provided with a low temperature fluid outlet at the upper end and a low temperature fluid inlet at the lower end, and low temperature fluid is transmitted in the shell from outside and flows from bottom to top along the outer wall of the heat exchange tube so as to gradually ice the water flowing in the heat exchange tube into tube ice through heat exchange. The whole ice making and unloading process can be controlled in an automated way and is suitable for automation production in large scale. In addition, the round heat exchange tube has a large heat exchange area and can ice an ice layer from the external circumference to the circle center, thereby achieving even heat exchange; the full closed heat exchanger can realize lowest loss of refrigeration capacity and achieve a most energy-saving and most effective heat exchange effect; and moreover, parts in contact with the water are all made of stainless steel or aluminum alloy, and thereby, produced ice blocks are clean and sanitary and can be eaten directly.

Description

technical field [0001] The invention relates to ice-making equipment in refrigeration equipment. The ice-making equipment uses the principle of heat transfer to exchange heat with water with a material colder than water, so that the temperature of the water drops below the freezing point and freezes. Specifically, it is a tubular Ice maker. Background technique [0002] Ice machines are mainly used to make fresh, store or cool daily necessities, and use water to make ice. The manufactured ice cubes can be used for freezing and keeping meat and fish fresh. According to the shape and size of ice cubes required by the market, the structure of the ice machine is also different. [0003] At present, the most commonly used ice machine in my country is the block ice machine. This block ice machine uses a refrigeration system to reduce the temperature of high-concentration brine to about minus 10 degrees Celsius, stores it in a brine pool, and uses a mixer to make the whole brine ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem solved by the present invention is: in order to overcome the problems that the existing ice machine cannot realize automatic control, the speed of ice making and deicing is slow, and the energy loss is large, etc., a tubular ice machine is provided, and the whole process can realize automatic control , suitable for mass production, and energy saving, good heat transfer effect
